The scoring system for badminton has changed in recent years. This was done to speed games up and make them more entertaining to watch. A badminton game is now played up to 21 points, and a point can be scored from every rally, regardless of who is serving. Under the old system a point could only be scored by the player holding the serve.
The main reasons for the change were:
- To make the sport more marketable
- To make easier to understand
- To reduce match time
- To make it more exciting for the spectators
The Badminton World Federation (BWF) laws for scoring and match play.
- A match consists of the best of 3 games of 21 points.
- Every time there is a serve there is a point scored.
- The side winning a rally adds a point to its score.
- At 20 all, the side which gains a 2 point lead first, wins that game.
- At 29 all, the side scoring the 30th point, wins that game.
- The side winning a game serves first in the next game.
Interval and Change of Ends
- When the leading score reaches 11 points, players have a 60 second interval.
- A 2 minute interval between each game is allowed.
- In the third game, players change ends when the leading score reaches 11 points.
- At the beginning of the game (0-0) and when the server's score is even, the server serves from the right service court. When the server's score is odd, the server serves from the left service court.
- If the server wins a rally, the server scores a point and then serves again from the alternate service court.
- If the receiver wins a rally, the receiver scores a point and becomes the new server. They serve from the appropriate service court; left if their score is odd, and right if it is even.
- A side has only one serve..
- At the beginning of the game and when the score is even, the server serves from the right service court. When it is odd, the server serves from the left court.
- If the serving side wins a rally, the serving side scores a point and the same server serves again from the alternate service court.
- If the receiving side wins a rally, the receiving side scores a point. The receiving side becomes the new serving side.
- The players do not change their respective service courts until they win a point when their side is serving.
